WEATHER DISCUSSION: Areas of light freezing rain continue to impact the Hi-Line through late morning on Monday. Roads are very icy region-wide, even in areas where temperatures have risen above freezing. The melt-refreeze cycle continues over the next several days creating dangerous road conditions and a higher risk of slip-related injuries. Minor street flooding will also be a risk as snowmelt continues.
Temperatures will be seasonable warm through midweek before falling closer to climatological normal. An atmospheric river event is going to continue funneling moisture into western Montana with low elevation steady rain and high elevation heavy snow on Tuesday and Wednesday. Scattered showers will be around east of the Continental Divide on Tuesday and Wednesday.
